Vespa 50/125/150/200/250/300
Suitable for gearboxes and reducers that require a single-grade transmission oil. Contains a friction reducer. API Service GL2 specifications.
Bardahl Classic Gear Oil SAE 80 is a 100% mineral single-grade transmission oil. The chosen viscosity provides constant lubrication under extreme loads. Bardahl Classic Gear Oil SAE 80 contains a minimal amount of additives and is fully compatible with brass, bronze, copper, and non-ferrous metals. It is suitable for period sealing materials (paper, cork, felt, and fabric). The excellent adhesion of the lubricating film helps ensure minimal wear, even after a prolonged period of inactivity.
Applications
Appropriate for the gearbox and transmission of classic cars that require a single-grade type gearbox oil.

The new reinforced axle shaft for Vespa smallframe engines is
made of high-strength steel with a corresponding vacuum carburizing
treatment.
The material used and the new sizing make the shaft
particularly suitable for tuned engines or with displacements greater
than normal (even up to 250 ccm)
Today, thanks to recent investments by some manufacturers, it is
possible to find on the market a wide range of very powerful thermal groups
that even exceed 40 horsepower.
I remind you that the Vespa smallframe engine was designed to last over
time and its power hardly exceeded 10 horsepower.
With these power increases, it is essential to adjust all mechanisms to avoid breakages and premature wear.
Example of the new sizing. The threading has also been increased to M16x1.25
